Detailed Description

The foregoing and other technical and scientific aspects, features and utilities of the present invention will be apparent from the following detailed description of the embodiments, taken in conjunction with the accompanying drawings of fig. 1-3. The structural contents mentioned in the following embodiments are all referred to the attached drawings of the specification.

Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

The embodiment I, tunnel fire monitoring device, including tunnel 1, its characterized in that, 1 horizontal interval in tunnel seted up two sets of first rectangular channel 2, two sets of first rectangular channel 2 in the longitudinal rotation be connected with first gear 3, first gear 3 by the power device drive, 1 inside wall vertical sliding connection in tunnel have

movable plate

4, 4 one end fixedly connected with of movable plate and the first rack 5 of 3 meshing of first gear, 4 lower extreme fixedly connected with of movable plate detect camera 6, 1 inside wall in tunnel be provided with protector, ensure to take place after the fire disaster, detect camera 6 and can not damage, detect electric connection between camera 6 and the controller.

When the embodiment is used, the first gear 3 is rotated by controlling the power device, the first rack 5 meshed with the first gear starts to move, the moving plate 4 acts along with the first gear, the detection camera 6 leaks out of the tunnel 1, the condition in the tunnel 1 is monitored, the protection device is opened, the moving plate 4 can be ensured to descend, once a fire breaks out, the first gear 3 acts, the first rack 5 meshed with the first gear starts to contract, the detection camera 6 is retracted into the inner side wall of the tunnel 1, the protection device is closed, the detection camera 6 is protected, and the first gear cannot be damaged by fire.
